Product Overview

The H961-U V1.0 Power Bank Charger Module is a professional-grade, multi-interface power management motherboard (PMIC) designed to control custom lithium-ion or lithium-polymer battery packs [context]. Acting as an all-in-one charging engine and synchronous boost converter, this slim-profile circuit board manages input current to safely recharge battery cells while boosting output voltage to run mobile gear. This intelligent module serves as the primary processing core for developers and makers looking to construct high-reliability custom portable power stations, emergency backups, or field chargers.

Advanced Input/Output Connectivity

The H961-U architecture features a highly versatile layout of five physical communication ports distributed across a low-profile green-mask printed circuit board:

Dual High-Current USB Type-A Outputs: Located along the top edge are two independent, robust USB ports designed to supply a steady 5V DC rail at up to 2.4A of continuous current. The left port features a distinctive bright yellow plastic tongue, identifying its native support for advanced fast-charging negotiation loops.
Modern Dual-Input Lane Charging: Built with both a modern USB Type-C port (far left) and a standard Micro-USB port (top middle). This dual-input design allows you to top off your custom battery pack using standard smartphone cables without requiring specialized power bricks.
Accessory Side Mechanical Switch (S1): A micro-tactile push-button located at the far right edge serves as a system wakeup trigger to activate the status screen or cycle standby power modes cleanly.

Intelligent Real-Time LCD Telemetry Screen

The centerpiece of the board is a custom segmented LCD screen that provides instant visual diagnostic data, eliminating the guesswork of basic multi-led dot indicators:

3-Digit Numeric Fuel Gauge: Displays precise battery capacity from 0% to 100%, reading data from high-accuracy internal voltage-divider lines.
Directional Status Metrics (IN / OUT): Explicitly indicates whether the board is currently absorbing power from a wall adapter to charge the batteries (IN) or discharging energy out to power a connected phone (OUT).
Protocol & Output Mapping Indicators: Features dedicated graphic tags like 5V 2.4A to confirm current outputs, accompanied by lightning bolt symbols and a dedicated QC (Quick Charge) label that blinks or illuminates steadily when fast charging is actively negotiated.

Premium Power Engineering & Safety Protections

Heavy-Duty 2R2 Power Inductor: The energy storage stage is driven by a low-profile, fully shielded 2R2 surface-mount power inductor. This component stores and transitions magnetic flux cleanly, minimizing conversion noise and heat during long boost cycles.
Dedicated B+ and B- Battery Pads: Large, highly visible gold-plated solder landing pads labeled clearly on the front face provide an ultra-low resistance connection point for hardwiring the positive and negative terminals of your lithium chemistry array (such as parallel 18650 or 21700 cell strings).
Multi-Chip Battery Safety Net: The onboard circuit trace includes automated hardware safeguards to protect your lithium cells against hazardous operating conditions, including over-charge protection, over-discharge voltage cutoffs, output over-current limits, and short-circuit isolation.

Common Field Applications

DIY 18650 / 21700 Power Banks: Transforming salvaged or premium new lithium cells into high-performance, personalized portable chargers for travel or camping.
Portable Field Prototyping Systems: Providing a clean, self-contained 5V power grid to run Arduinos, Raspberry Pis, and low-voltage field telemetry devices during outdoor testing.
Solar-Assisted Power Hubs: Wiring the module’s input pins to a regulated 5V solar panel line to construct an off-grid, sun-powered device charging kit.
Emergency Flashlights & Survival Gear: Serving as the master control circuit board inside custom-built multi-cell work lamps and outdoor emergency power kits.
